Starch is a major source of energy for the diet. Starch is made up of glucose molecules linked together forming linear chains and also branching chains. These chains are tightly packed and organised into granules where they are stored for energy in plants. By breaking this organised system and releasing the glucose, humans are able to use starch as a source of energy.
